200-4r accumulator valve train assembly

[stovebolt 34]

Might be a stupid question but please bear with me . . . . been a while since I cleaned and reassembled the valve body . Took the accumulator bushing , valve and spring out for cleaning . When reassembling I noticed the roll pin did not go all the way through the bushing ( no hole in the bottom of the bushing ) . The roll pin goes in flush with the top of the valve body . If I remember correctly the hole in the valve body goes from top to bottom . Something strange about this . What am I missing ???
Transmision aeems to work OK . Any opinions on the one Sonnax sells ???
Thanks in advance . . . . Gordon
